Size Scaling of the Electrochemical Performance of Ti3C2Tx MXene Microelectrode Arrays for Electrophysiological Recording and Stimulation

open access: yesSmall, EarlyView.
This study evaluates Ti3C2Tx MXene‐based microelectrodes across a range of diameters (25–500 µm) and elucidates their recording and stimulation capabilities for bioelectronic applications. Several electrochemical measurements—supported further by equivalent‐circuit modeling—revealed enhanced recording and stimulation capabilities of the MXene ...

Mechanically Enhanced, Antibacterial, and Double‐Network Hydrogel Flexible Sensors for Sleep Apnea Monitoring

open access: yesSmall, EarlyView.
This report describes the preparation of an antibacterial hydrogel sensor from a polyvinyl alcohol/silk fibroin double network, tannic acid‐coated liquid metal, and copper particles, with an ethanol post‐treatment using a multi‐level structural regulation strategy. The obtained hydrogel is evaluated in the context of respiratory monitoring.

Single Cu Atom Sites on Co3O4 Activate Interfacial Oxygen for Enhanced Reactivity and Selective Gas Sensing at Low Temperature

open access: yesSmall, EarlyView.
Atomically dispersed Cu sites on Co3O4 nanoparticles establish well‐defined Cu–O–Co interfacial linkages that promote lattice oxygen activation at markedly reduced temperatures. This structural and electronic modulation yields over twenty‐fold higher low‐temperature formaldehyde sensing responses than CuO nanoparticle analogues, enabling selective and ...

Immune escape mechanisms revealed by multifunctional nanoprobes targeting PD‐L1 in hepatic cancer progression

open access: yesVIEW, EarlyView.
The ICGB@Apt nanoprobes are designed to specifically recognize immune checkpoint molecules such as PD‐L1, thereby enabling precise monitoring of the progression from liver cirrhosis to HC. By binding to PD‐L1 on tumor cells, ICGB@Apt visualizes immune escape events and tumor metastasis while simultaneously reflecting the dynamic interaction between ...

Surface Micro‐Discharge Plasma for Multiple Teeth Bleaching: Efficacy, Mechanism and Safety

open access: yesHigh Voltage, EarlyView.
ABSTRACT Hydrogen peroxide (H2O2) is the commonly‐used bleaching chemical in clinical practice, but its excessive concentrations can cause tooth damage. Atmospheric pressure cold plasma is considered a promising new technique for tooth bleaching. Surface micro‐discharge (SMD) devices can generate large‐scale plasma, which holds potential for treating ...

Navigating complexity: A relational perspective on generative AI adoption in government

open access: yesAustralian Journal of Public Administration, EarlyView.
Abstract This research note presents preliminary findings from exploratory research examining how Australian public servants understand and use generative AI (GenAI) in government work. Drawing on 37 interviews across 22 agencies, we highlight the importance of a relational view of GenAI adoption, that is, the co‐creation of meanings that emerges from ...

Capitalizing flood risk protective measures in residential real estate

open access: yesReal Estate Economics, EarlyView.
Abstract This study utilizes 1.4 million residential transactions incorporating flood hazard estimates derived from a nationwide elevation model and hydrological data to examine the role of flood protections to mitigate the negative impact of flood risk on home prices.
